after dialogue 1 play an animation and play dialogue2,after conversation1 play an animation and play conversation2

hello I want to know when one of the dialogue button(1) was click, how can I play an animation right away and DON'T INTERRUPTED BY PLAYER ?

(If player can move, I can't continue the dialogue.)

After the animation finished, player can click the diaogue button(2) to continue the game.

I use dialogue system for unity to start the dialogue. Here is my question image:

thanks
